[0020] The application will be further described in detail below in combination with examples.

[0021] Reference Figure 1 , Figure 2 As shown in the figure, the modular self-locking base structure of the modular self-locking vehicle one-key starting device provided by the application comprises:

[0022] The base assembly is integrally formed by aluminum alloy, the back is pre-coated with 3M VHB high-adhesion glue layer for bonding with the vehicle body; the front of the base is provided with symmetrically distributed T-shaped guide rails 102, the inner side of the guide rails is provided with stepped limiting protrusions 104; the both sides of the base are integrated with elastic buckles 103, the inside of the buckle 103 is embedded with spring steel sheets 105, and the end of the buckle is connected with a release button 106.

[0023] The device body assembly is provided with a T-shaped sliding groove 202 matched with the sliding rail at the bottom of the body 201, and a rubber damping layer is arranged on the inner wall of the sliding groove; the side of the body is provided with a buckle groove 203 corresponding to the elastic buckle, and a magnetic adsorption sheet 207 is pre-buried in the groove to form auxiliary locking with the magnet 109 in the middle of the buckle.

[0024] The bidirectional anti-dropping design of the application comprises:

[0025] Mechanical locking, when the device body is pushed along the sliding rail, the limiting protrusions 104 rub against the rubber layer in the sliding groove to generate frictional damping, until the end of the sliding rail triggers the elastic buckle 103 to pop up and lock; the spring steel sheet 105 of the elastic buckle 103 is in V-shaped structure, and is normally pressed outward, and the locking can be released only by pressing the two release buttons 106 at the same time.

[0026] Vibration suppression, a silica gel damping block 107 with a Shore hardness of 60±5 is arranged at the end of the sliding rail to absorb high-frequency vibration in vehicle driving; a polyurethane foaming layer 110 is filled between the base and the vehicle body to reduce resonance transmission.

[0027] Wireless power supply and emergency interface comprises:

[0028] Wireless power supply module, the base is embedded with a Qi standard wireless charging coil 108, the output power is 15W, and the power transmission is realized when the distance between the receiving coil 204 and the base is ≤5mm; an electromagnetic shielding layer is arranged around the receiving coil 204 to prevent interference with the vehicle-mounted electronic equipment.

[0029] Emergency physical interface, the bottom of the body is provided with a spring contact pin 205, and the base is arranged with a copper conductive sheet 111 at the corresponding position; the contact pin is treated with gold plating, and when inserted, it is automatically pressure-welded with the conductive sheet to conduct, and the contact resistance is <10mΩ.

[0030] During installation, first clean the instrument table installation area of the vehicle body, remove the adhesive film on the back of the base 101, press for 30 seconds to make it bond with the vehicle body; let stand for 24 hours to make the adhesive layer completely cured and the bonding force ≥3MPa.

[0031] Align the T-shaped sliding groove 202 of the device body 201 with the base slide rail 102 and push it in the guide rail direction; when a "click" sound is heard and the body surface LED indicator light turns green, it indicates that the elastic buckle 103 has been locked; open the mobile phone APP to confirm that the Bluetooth signal strength is >-70dBm and the angle deviation prompt is <1.5°, short press the start button to test the vehicle ignition response, and long press for 3 seconds to activate the wireless charging function; simulate the vibration environment frequency of 20Hz and the amplitude of 2mm to test the device displacement <0.1mm.

[0032] In some emergency repair scenarios, when wireless power supply fails, continue to push the body to the end of the slide rail by 2mm, so that the spring needle contact 205 is in close contact with the conductive sheet 111; the system automatically switches to wired power supply mode, and the APP prompts "emergency power supply is enabled".
